100 expensive pictures

Michele, a stuck shutter is a common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

The shutter is jammed closed. This blocks the light from reaching the image sensor. This problem can generally be fixed without parts, price will be $100-150 for labor from a professional. Depending on the purchase price of the camera, you may be better off getting a new camera.

The FX format uses a sensor very close in size to a frame of traditional 35mm film, about 36mm by 24mm. The DX format uses a smaller sensor, about 24mm by 18mm. The smaller sensor allows the camera to be smaller (compact point&shoot cameras use sensors much smaller) and also are less expensive.

The most visible effect of the difference is the so-called lens multiplier. The smaller sensor uses only the central portion of the image projected by the lens, in effect multiplying the focal length of the lens. In this case, a 100mm lens attached to a DX camera will give just about the same picture you would get with a 150mm lens attached to a FX camera.

In general, FX lenses will work fine on DX cameras, taking into account the lens multiplier mentioned above. DX lenses will not work properly on FX cameras, since the smaller DX lens won't always capture the full images needed to cover the larger FX sensor. Some FX cameras automatically switch to DX mode when it detects a DX lens.

If the symptoms are similar as it was ccd imager problem then contact again with Canon for again free replacement of ccd imager chip in camera.
Can you post an image here that shows purple problem?
And if its lens problem as said by Canon then new camera would be better option instead of spending on its repair.
Thanks.

I am having the same problem. I bought a Tamron zoom lens as an add on. This lens costs more than the camera and yet images are not as sharp as i would expect from such a highly touted camera. My Kodak Z740 point and shoot gives sharper prints. This is very frustrating. I bought Rebel for Dummies and still am having the same problem. Very frustrating

You can pull off the other one if you want. To put it back in your basically going to have to take apart the camera. The "Shutters" on the outside is nothing more but to protect the lens will its in the camera. The actual shutter is inside the lens that open and closes very quickly when you take a picture.

Think of it this way, the shutter in the lens opens up to let in light that shows the image to the sensor behind the lens. Then it closes to "finish" capturing the light".

The "shutters" or "doors" on the outside do not move once you take a picture. They only close once the lens retract. (When the camera is turned off or idles)

Hope this has been helpful.

Hi
Had the same problem a few months ago.There was a high pitchedwhisltle and I think the screen said "lens fault.turn off camera" or something similar.Bought a G9 to replace as the 7 was out of guarantee but sent the 9 back to the e-bay reseller as it was obviously secondhand with grit around the lens ring and the viewfinder.Ebay never again!.So 3 months ago ago I tried the G7 again with a fresh charged battery before I consigned the camera to the loft.I noticed that each time i switched on the whistle and message was there but the lens extended slightly further each timeso I kept rebooting until the lens was fully extended.Turned the camera off and on again and everything was back to normal.It seems that this may be Canons protocol when a camera goes back.Its been absolutely fine until today.It wont boot up at all.I have tried 2 fresh charged batteries and its dead.Any ideas anyone?

After some inspecting of the camera it seen the issue lies with the lens, not the camera itself so don't go banging the camera up or you might damage some other part and the camera will be broken for real. Inside the lens is a closer which block the internal system from capturing image. The closer look just like the one you see before turning on your camera but it's smaller and it's inside the lens way in the far back. Look carefully and you'll see it - you will see the closer if your screen is black while in capture mode otherwise you will see a nice round glass (the internal lens for capturing image/video).

Think of if like this, imagine an eyeball with its eyelid close. That's what happened when the screen is black while in capturing mode.

HOW TO FIX IT: In order to fix the black screen while in capture mode and cost as little damage to your camera as possible, simply turn on the camera in either picture or video mode and look inside your lens, there should be a closer in the far back end. Gently hit the lens a few times until you don't see the closer no more and only a round glass and your camera should begins capturing image and video again.

Good luck to you all. And remember don't use anger to force your camera to works or you will regret it.

serious problem im afraid.did it get a knock??The problem is the lens block assy is damaged and needs replacement,would be cheaper to replace it as very little can be done to repair old assy and usually needs new lens assy which can be very expensive.

Hopefully someone has a better answer, but no mater what mode its in, its been my experience these cameras don't like to be dropped. Sometimes they can be repaired, its just a matter of finding someone who or return camera to factory for a repair.
